Enum Opening 

pub enum Opening {
    FromJob,
    Inherited,
    WithPerson,
}

How the first user message opens: kernel’s, because run_started records it (crates/kernel/Spec.lean §8-82-1). How a run’s first user message opens.

Exhaustive, and the choice is made once by the city that wrote (or did not write) the job file. It is not a formatting preference: a session working from an assignment and a session talking with the person want different first words, and inferring which from an empty string would make the emptiness of a goal mean two things.

It lives here rather than beside the conversation that writes it because run_started records it, and the ledger’s payloads are this crate’s; runtime::conversation re-exports it.

Variants

FromJob

Somebody wrote the task down; the job file’s text is in the prefix.

Inherited

Somebody wrote the task down for a mother, and a branch is rebuilding her conversation: her job file lives in her room, not in the branch’s prefix, so the task travels in the message.

WithPerson

Nobody did; the person is on the other side of this message.
